Supply Zirconia Tube Zro2 Ceramics Zirconia Sleeve Industrial Ceramic Products
Zirconia (Zro2) ceramic offers a combination of high hardness, wear and corrosion resistance, while exhibiting one of the highest fracture toughness values among all ceramic materials.
There are several grades of Zirconia available – the most common of which are Yttria Partially Stabilized Zirconia (Y-PSZ) and Magnesia Partially Stabilized Zirconia (Mg-PSZ). Both of these materials offer excellent properties. The operating environment and design will dictate which grade is suitable for specific applications.
